How does the body prepare itself for a future infection by the same food poisoning?

Before you eat or cook anything you should ALWAYS check the date it is the safest thing to do.And if you food at home or in a restaurant doesnt taste right DONT eat it... send it back or tell somoeone it is yuckie!

To fight an infection that has taken hold already the body releases lymphocytes. These come in two main forms killer t lymphocytes and b lymphocytes. The body recognises that cells in it are not "self" cells because they have antigens that are not recognised. When these cells show up the right antibodies to bind these antigens are required to fight the infection. Killer t cells have antibodies stikcing out of them adn when the find cell with the counterpart antigen then destroy them. b cell release a=two heayed antibodies into the blood which each bind two antigens and (and so two infection cells) together. The latter process creates large collections of infection cells that machrophages will later come and digest. The problem with this defens is that is can take time to find the correct antibodies and to recognise the antigens and so the infection is allowed to build up for a while. So after the infection is beaten many of the lymphocytes are destroyed apart from a few which are left as memory cells that will allow for a faster recognition and defens the second time around. Note: This is not specific to food poisoning but as far as i am aware there is no specific mechanism for this.
